HOLDER FOR CARBOYS.

noonece.

To (ZZZ whom it may concern Be it known that 1, Homer M. MoConD, a citizen of the United States. residing at Minneapolis, in the county of Hennepin and State of Minnesota have invented certain new and useful Improvements in Holders for Carboys, of which the following is a specification.

My invention relates to an improvement in carboy holders and has for its object to provide a device which will hold a carboy securely upright when its contents are not needed, and will permit its easy and safe handling when any part of its contents is needed.

Heretofore the handling of carboys containing corrosive acids has been both difficult and dangerous. The weight of the carboy and its awkwardness in handling have made two men necessary in order to handle the same without danger to the men or waste of acid. It is not safe when so handled and many instances of serious injuries received while so emptying the carboys are known. The use of acids has been and is steadily increasing. Many industries in all sections of the country require acids and they generally receive their supplv in carboys. The requirements of storage batteries, soda fountains, etc., demand a great deal of acid. This is almost invariably supplied in carboys.

My invention provides a method by which one person can more easily and safely handle a carboy than can two without its aid. By its use a large or small quantity of acid can be removed and the carboy returned to its vertical position and there locked.

A further object of my invention is to provide a carboy holder and tilter that will not depend upon the strength of the carboy itself in suspending it for tilting. Carboys are so heavy when full, and are subjected to such strains in transportation and handling, that to suspend the carbov in a holder which depends for its safety on the frame of the carboy itself is a dangerous thing. The use of such devices has proved very unsatisfactory. My invention provides a strongly built box into which the carboy is inserted and locked. In this way but very slight strain is placed on the frame of the carboy itself. with consequent less liability of its breaking.

A. further object of my invention is to Specification of Letters Patent.

provide means by which the carboy holder is strongly supported when the carboy is being inserted therein. This is accomplished by using the hinged front, which is let down to insert the carboy, as a support resting on the bottom frame piece. In this way the holder is adequately supported when support is greatly needed.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form, Figure 1 is a front elevation of my invention, Fig. 2 is a side elevation, Fig. 3 is a plan view and Fig. 1 is a side elevation showing my inven tion in tilted position. All these figures show the outline of a carboy and other de tails dotted in. Figs. 5 and 6 are detail views of the mechanism for holding the carboy in the box.

In the construction of my invention frame pieces 10, 11, 12 and 13 are joined together to form a base upon pieces 12 and 13, on which are mounted uprights 14 and 15 securely fastened thereto and made more seuprights 14 and 15 are swinging supports lSand 19 to which is attached abox 20 built solidly on three sides and the bottom and of a size sufiicient to permit a carboy to be placed therein.

To the front side of box 20 are attached door pieces 21 and 22, door piece 21 being hinged to the bottom of box 20 and top piece 22 being hinged to door piece 21. Top piece 22 is constructed so as to fold out and tightagainst door piece 21 and they are of such length that when both 21 and 22 are folded under box 20 they rest directly on frame piece 10 and serve as a support to the box 20 when the carboy is being inserted. On the sides of box 20, adjacent to top pieces 22, are located latches 23 and 2-4: which serve to hold the carboy in box 20 when the carboy has been inserted and the door pieces swung up. Catches 23 and 24 are provided with springs so that when the top piece 22 is thrust against them they spring open and then shut over the top piece 22.- To' prevent oscillation. of box 20 except when desired,

pin 25 is provided fastened to upright 15 by a chain 26. Pin 25 is inserted through holes in upright 15 and when box 20 is upright or in vertical position pin 25 is pushed through holes in upright 15 into holes in stinging support 19, thus securely locking box 20 in vertical position. For the purpose of holding the carboy against the bottom of box 20 when it is tipped to permit the drawing off of acid, a rod 26 is provided having a hook sharpened portion 27 adapted to hook into the top of the carboy. Rod 26 is slidably mounted upon the rear side of box 20 by means of a keeper 28 firmly fastened to the top of box 20 by means of a slot 29 which is provided in rod 526 near its bottom, and has a bolt 30 passing through the rear side of box 20 and through slot 29. Bolt 30 is provided with a washer 31 and a hand nut 32, which permits rod 26 to be adjusted to any height in the range of slot 29 and locked in that position by tightening the nut 32. Roughcned or toothed projections 33 are provided on rod 26 to further insure it from slipping while holding the carboy in box 20. A. sharpened iron is provided on the inner side or top piece 22 for the purpose of pre venting the front of the carboy from slipping up out of the box 20 when the carboy is tilted.

In operation my device is placed where the carboys of acid are handiest for the purpose needed. The iron rod on the rear of the box is raised enough to permit the complete insertion of the carboy. The swinging box is locked by means of the pin and the hinged front part dropped down and turned under the box until it rests on the frame piece therebeneath. In this position the box is strongly supported for the insertion of the carboy filled with acid. its these carboys when filled are very heavy, a sup port of this kind is necessary to obviate the danger of accidents. The carboy is now in sorted into the box, the hinged portion is swung up and locked into position by means of the latches on the sides of the box. When so locked in, the sharpened iron on the inside of the hinged portion enters into the wooden side of the carboy and holds it from slipping. The long iron rod located at the rear of the box is now drawn down until its sharpened curved portion begins to enter the wooden top of the carboy. In this position it is firmly locked and the carboy is now held securely in place in the swinging box. The device is so constructed that the center of gravity of the full carboy is lower than the pivoted points of attachment, so that when tilted and released the carboy will at once assume a vertical position. In pouring from the carboy as held in my device it is only nec ssary to overcome the resistance present because of this lowered center of gravity, hence the operation is an easy one.

menace The carboy if released returns at once to the vertical position so that the danger to the operator and the liability of waste of acid are reduced to the minimum.

The advantages of my invention are obvious. by its use an operation requiring two men, great effort and even then entailing danger of accident and of waste of acid, is made an easy operation for one man with danger of accident and of waste eliminated. By it, one man can handle a carboy of acid much surer than can two in the old way. The vast amount of acid that is now handled. in commercial industries where unskilled labor is employed makes such a device a necessity in order to avoid accidents which might be very serious and expensive f r the employer. It is comparatively inexpensive to manufacture and will supply a wide spread need.
